Title: Detecteur de flamme et son procede d'utilisation
Inventor: MURGU CRISTIAN
IPC: F23N5/08
Filed: 2001-05-28
Abstract: L'invention concerne un détecteur de flamme conçu pour détecter la présence d'une flamme dans un brûleur. Le signal provenant du détecteur est transmis à un amplificateur adjacent au détecteur, et amplifié sans que le signal du capteur soit contaminé par le rayonnement en mode commun. Le signal amplifié de manière sélective entre 15 et 80 Hz est traité par un microdispositif de commande situé à distance du détecteur et de l'amplificateur, lequel microdispositif de commande peut interrompre ou poursuivre le fonctionnement du brûleur. L'intégrité du circuit de connexion entre l'amplificateur et le micro dispositif de commande est également contrôlée et l'arrêt du brûleur se produit s'il y a un défaut dans ce circuit.
Patent CA-2000715-A1 (CA)
IPC: A45D40/26
Filed: 1989-10-13
Abstract: The invention provides a dual cosmetic applicator and container for applying cosmetic, especially mascara, to the eyelashes in which a pair of eyelash brushes engage each other on the inside of a container holding a quantity of cosmetic.  When an eyelash brush is removed from the container its bristles rub against the bristles of the other brush so as to mix the cosmetic which is applied to the brush.  This mixing action tends to thin thixotropic cosmetic like mascara, making application of mascara to the eyelashes easier.

Title: Application of multiple enzyme blend to control industrial slime
Inventor: WIATR CHRISTOPHER L
IPC: A01N63/50
Filed: 1989-10-26
Abstract: A method of attacking and removing microbial slime in slime covered surfaces and maintaining a slime-free surface as in exposed cooling tower surfaces and in waste water treatment and paper making.  This method comprises utilizing an enzyme blend in 2 to 100 parts per million (ppm) of beta-glucanase, alpha-amylase and protease.  Such enzyme blends have been found specifically to digest microbial slime and reduce microbial attachment and biofilm.  A specific combination of polysaccharide degrading enzymes is a ratio of 2 parts beta-glucanase to 1 alpha-amylase to 1 protease utilized in 2-100 parts per million.  Broadly, the alpha-amylase must be at least 1 and the protease may vary from .5 to 1 part.

Title: Method of and apparatus for reducing energy consumption
IPC: H05B39/04
Filed: 1990-01-18
Abstract: The proposed invention is an energy saving load control device   primarily  intended  for  inductive  loads   (i.e., fluorescent  lighting,   motors,  etc.)  operating  from  an alternating  current  (AC)  source.    The  proposed  device switches the load voltage off at arbitrary positions in  the sine wave and simultaneously provides a commutating path for any inductive current.  By switching the load voltage on and off  and providing a commutating current path reduced energy consumption is realized.
Patent CA-2008482-A1 (CA)
IPC: D21F1/00
Filed: 1990-01-24
Abstract: This disclosure shows a novel  shaped pintle wire for papermachine clothing.  The intended use of the pintle wire is to close a pin seam by joining the loops formed by machine-direction yarns at each end of an open-ended papermachine fabric.  The present pintle has a non-circular cross section with a major dimension and a minor dimension.   The major dimension stretches the loops and reduces seam gap.  The minor dimension is approximately equal to the thickness of the fabric under load.  Both serve to reduce the marking of the paper sheet by the seam region.

Title: Inspectable vault system for the disposal of radioactive waste having a liquid collection system
Inventor: MEESS DANIEL C
IPC: E02D31/00
Filed: 1990-03-29
Abstract: ABSTRACT OF THE DISCLOSURE      A   vault system is disclosed herein  for  the disposal of hazardous waste formed from vault cells, each of which has a liquid collection and monitoring system.  Each vault cell comprises a liquid impermeable floor slab having a drainage channel for collecting liquids, a wall assembly disposed around the periphery of the floor slab. a ceiling slab overlying the wall upper edge of the assembly,  and a monitoring and inspection aisleway disposed between the wall assembly and radioactive waste stacked within the vault cell that encompasses the drainage channel to render it both observable and accessible.   The floor slab includes a plurality of feeder channels arranged in a rectangular grid pattern that ultimately drain into the drainage channel and are arranged such that each feeder channel collects liquid from a different rectangular zone within the floor slab so that the location of a leakage condition may be generally determined by observing which feeder channel conveys liquid to the drainage channel.  A drainage conduit located out of the vault cell includes a transparent trap with a color float for indicating whether liquid is present in the conduit. Each drainage conduit is drained into a manifold conduit which is in turn connected to a collection tank.   The flotation device of each drain conduit is rendered accessible and directly observable by means of a subterranean tunnel that links the ends of all such drainage conduits together.

Title: Prefabricated window for installation in an inclined roof
Inventor: BORRESEN BJARNE
IPC: E04D13/03
Filed: 1990-10-15
Abstract: A bracket for fixing a prefabricated window to roof boards or sheathing in an inclined roof is already secured to the window main frame during the factory assembling of the window. The presecuring of the bracket is effected by a screw inserted through a hole in a positioning member which through a connecting portion consisting of a bridge and a rodlike member is integrally connected with one side edge of a first leg of the bracket. The first leg continues at its lower side into a second leg at right angle to the first leg.      Before packaging the window for transportation the first and second legs are swung into abutment on the main frame by turning around the connecting portion.      When the window is to be installed in the roof the first and second legs are swung through an angle of 180° until the first leg abuts against the positioning member. In this position mounting screws are through the overlapping holes screwed into the main frame. Then the window is secured to the roof hoards by driving screws or nails through the holes in the second leg into the boards.

Abstract: METHOD AND MEANS FOR DETERMINING AIR MASS IN    A CRANKCASE SCAVENGED TWO-STROKE ENGINE Abstract of the Disclosure The mass of air available for combustion within a cylinder of a crankcase scavenged two-stroke engine is obtained by estimating the mass of air trapped within a crankcase chamber, prior to its transfer to the associated cylinder combustion chamber. The estimate for air mass is derived from the product of pressure of the air in the crankcase chamber and the crankcase chamber volume at a selected engine cycle position during that portion of the engine cycle when the air is trapped and undergoes compression within the crankcase chamber divided by a factor containing the trapped air temperature at the selected engine cycle position.
